(PhTe)2-mediated intramolecular radical cyclization of o-ethynylaryl isocyanides leading to bistellurated quinolines upon visible-light irradiation.

Upon treatment with (PhTe)(2) under visible-light irradiation, o-ethynylaryl isocyanides underwent intramolecular radical cyclization with introduction of telluro groups, affording the corresponding bistellurated quinolines.
